Claims (1)

[Claims for Utility Model Registration] 1. Between the surfaces of a superstructure and a support structure that supports the superstructure that face each other in the direction perpendicular to the bridge axis, one surface has a hemispherical convex portion on its upper surface. The lower shoe is fixed, and the hemispherical convex portion is slidably fitted into the hemispherical concave portion of the bearing plate, which is fitted into the circular concave portion on the lower surface of the intermediate platform to which the sliding plate is fixed. The intermediate shoe is pressed toward the lower shoe by a pressing member via an elastic body, and the upper shoe is fixed to the other side, and the sliding plate of the intermediate platform and the upper shoe are connected to the bridge. A bearing device that is arranged facing each other with a gap in the direction perpendicular to the axis. 2. An annular groove is formed on the outer peripheral surface of the intermediate platform, and an elastic body is disposed in the annular groove, and the elastic body is connected to the annular bottom fixed to the lower shoe and from the inside thereof to the annular bottom. It consists of a cylindrical rising part extending vertically and an annular pressing part bent inward from the end of the rising part, and is pressed by equally divided pressing members, whereby the intermediate platform is pressed against the lower shoe side. The supporting device according to claim 1 of the utility model registration claim, which is suppressed by: 3. A plurality of convex portions having bolt insertion holes projecting outward are formed radially on the lower peripheral edge of the intermediate stand,
An elastic body is disposed on the convex portion, and the elastic body is pressed by a suppressing member consisting of a pressing bolt inserted through a bolt insertion hole and a washer fixed to the bolt, thereby pressing the intermediate platform toward the lower shoe side. A supporting device according to claim 1 of the utility model registration claim.
